Carl Sagan: Cosmos, Pale Blue Dot & Famous Quotes

Called “America’s most effective salesman of science” by Time magazine, astronomer Carl Sagan spent much of his career translating technical scientific explanations to make them easily digestible by the general public. Described as a natural teacher, he educated not only through classroom lectures but also through interviews and on television shows. His 13-part TV series, “Cosmos,” has been seen by over 600 million people in more than 60 countries. The show was so popular it returned to television in 2005.
